Create a table summarizing data layers within each MTBS fire. Layers were assembled and reduced in Google Earth Engine, then the summary file exported to Google Drive. Downloaded the summary table locally from Google Drive, then ran this script to visualize and explore the data.
UPDATE: This script has been updated to filter for only ponderosa-dominated fire events (NOW COMMENTED OUT: with greater than 50% GEDI coverage). Additional metrics have been added, such as % USFS land, fire severity homogeneity, and burn severity amounts. Code hidden for ease of reading.

Note that a substantial part of the Hayden Pass fire is in a wilderness area, making it impossible for us to fly drones over that part of the fire. However, this part of the fire would likely be difficult to get equipment into, so we probably wouldn’t be flying there anyway due to the effort involved.
